To all whom 'it may concern:

Be it known that I, JEFFERSON Davis METCALF, a citizen of the United States, residin .at Gloster, in the county of Amite and tate of l\![ississippi, have invented new and usefulA Improvements in Scrubbing-Machinos, of which the following is a specification. A

The invention relatesv to an improvement in scrubbing machines designed primarily for manual propulsion and adapted to be automatically operated to insure an effective scrubbing operation during such propulsion.

The main object of the present invention is the provision of a scrubbing machine constructed to provide an automatic rotation of the scrubbing brush during the ropulsion of the machine and having mop c amps in advance and in rear of the scrubbin brush, the

construction including a receptac e mounted in advance of the brush and adapted to deliver a cleansing luidtoi'` the surface being operated upon.

The invention will be described in the following speciiication, reference being had particularly to the accompanying drawings, in whiche- Figure 1 is a plan of a scrubbing machine constructed in accordance with mv invention, Fig. 2 is a longitudinal centralI section,

artly in elevation of the same, the mops eing shown in position, Fig. 3 is a transverse section on line 3-3 ofFig. 1.

Referring particularly to the dra-wings, my improved scrubbing `machine comprises supporting wheels l and 2 mounted upon a divided axle including sections 3 and 4, the wheel 1 being loose upon the axle section 3,

While the wheel 2 is fixed to the axle section 4.

The main frame 5 is hung upon the axle, being lsupported in blocks 6 loosely encircling the axle adjacent the respective wheels. The

main frame is of rectangular outline comprising side bars 7, a forward cross bar 8, and a rear cross bar 9, said main frame being preferably constructed oi a siiwle length of wire rod to insure the desired lightness. lhe forward cross bar S on the main frame is provided with a series olf clamping members l() formed by Iprojecting said cross bar into aconsecutive y arranged series of U-shaped members extending rearwardly from said cross bar and lying in the plane of the side bars 5. At the connection of the main Jframe 5 with the block the side bars ol said frame are bent upwardly into loop form, as atl 1.1 and seated in a peripheral Crroove 12`orined 1n the respective blocks, w ereby the main length of the frame 5 is arranged below the supporting axle, as clearly shown in Fig. 3. Below the blocks 6V the side bars 7 of the main frame are connected by transversely arranged brace bars .13, extending from. one

rcarwardl r from the blocks in approximately horizonta plane.

A clamping member 14 is arranged to cooperate with the clam ing member of the main frame, said member 14 being preferably constructed of a single length o` wire rod bent to provide side bars 15, a relatively rear cross bar 16, and a forward cross bar 17. The forward cross bar 17 is bent to rovide a series of'U-shaped clamping mem ers 18 projected at right angles to the plane of the side. bars 15, and of such size that the loop portions thereof will, when in clamping position it within the U-shaped members l0 of the main trame. The cross bar 16 is provided with horizontally disposed .hi-shaped members 19 forming a supporting section, as

will presently appear. The clamping mem-y .ber 14 is connected to the side bars of the main frame by ring connectors 20 encircling the side bars 7 and 15, said clamping'mem'- ber 14 being of a size to dispose the supporting section 19 about midway between the forward end of the main frame and the laxle of the machine.

A rear mop clamp is supported from the mainframe in rear of the axlefcomprising a clamping member 21, preferably of wire rod, bent to provide a series of horizontally arranged U-shapcd proj eetions 22, and a clamp member 23 comprising a rectangular framev having a rear cross bar 24 bent to proiride vertically projecting U-shaped sections 25 and designed to [it betweenthe sections 22 of the member 21, thereby providing a clampsimilar to that described i'or the `forward end of the frame. The clam )ing member 21 is secured to the side bars o the frame through integrally formed rings 26 vembracing,said side bars in a position to dispose the U- shaped nn-nnbers 22m advance of the rear cross bar 9 of the main frame, the clamping member 23 being also secured to the side bars of the main frame by forming the juncture of the side bars and forward cross bar of said clamping member with -eyes to encircle the sidebar 7.

U-shaped brace members 27 project from the respective side bars 7 -of the main frame adjacent the aXle, eacli of said'U-shapedv .tive cross bars 28 'are tied together adjacent their ends by binding wires' 29, and intermediate said connections are bent to engage a peripheral groove 30 formed in a horizontally disposed bearing block 3l. The brace bars 13 are also centrally formed to engage and support a second bearing block 32, said blocks being'vertically alined and serving to rotatably support the brushy shaft 33.A A brush 34 of any desired or preferred construction is secured to the lower end of the shaft 33 below the block 32, the brush being so disposed that theo erative surface thereof is approximately/a 'ned withthe bearing points of the supporting-wheels 1 aiidZ. Ihe fixed section 3 of the axle is preferably offset or cranked, as at 35', to avoid interference with the ybrush shaft, and said shaft is provided' above the axle witha bevel gear 36 n is claimed as new, is:-` y

maintain'e in mesh with a bevel gear 37 formed oir-the movable section 4 ofthe axle, whereby/forward movement 'of the scrubbing machine will impart a continuous rotary movement to the brush.

tivelyT rear end with the U-shaped brace bars 27, vvextending therefrom at a forward and downward incline to and connected with the central portion of the rear cross bar 9 ofthe main frame. The beam l38 supports the o erating. handle 39, .the forward end of w 'ch is of slightly conical form and designed to be removably inserted in a helically lis provided with ahinge cover 45 closing its vupper end, the .outlet 44 being normally closed by a plug rod 4f), vthe upper end of which terminates above lthe u per edge of the receptacle proper, yso that t e outlet 44 may be opened to permit escape of the cleans- A brace beam 38 is connected at the relaing fiuid contained in the receptacle without the necessity of the operator reaching into said fluid. v

With the parts'assembled as describedtlie receptacle 42 is provided with. the desired quantity of cleansing fluid and inops 47 secured to the forward and rear clamping menibers by springing the clamping sections thereofy apart and inserting the end of the lmops, the return of the sections yto normal position through their own resiliency clamp ing the mops in place. In the forward movement of the machine under manual propulsion, the cleansiirg lluid from the tank 42, is, after removal of the lug 46 delivered to the surface to be scrub )ed immediately in advance ofthe brush 5 the brush is rotated under the power of one ofthe supporting i and arrangement of parts described, it is obvious that various' modifications and changes may be resorted to without materially alter'- ing the function of the machine, and 1,'therefore, wish it understood that I consider as within the spirit of the present invention all such changes and variations as'v may fall vwithin thescope ofthe appended claims.

Having thus described the invention what A scrubbing machine c om rising a main frame constructed of wire, a rush rotatablysup orted thereby, and a mop clamp carried by t ie forward end of the frame, said clamp` comprising one member formed inte-l gral with the 'frame and a cooperating nieinl be'r 'carried by the'frame, said members being arranged for cooperation through their m-v heientl resiliency.
